The purchase of the product was handled efficiently and was delivered promptly.
I installed one of the coils (first one from the pack) in to my vape pipe on 23/10/18, ready to be used the following day. The day after the install, around about midday, I noticed some of the cotton on one side of the coil wasn't there. I'm not sure if it wasn't there initially, prior to install, or if it has corroded in the tank.
Within a space of less than a day, the product had clear signs of 'wear and tear', which doesn't fill me with confidence. I shall check the remaining coils and see if there is a product fault across the board or if this was a one off. However, so far, i'm not overly impressed.
